  • Using ZeroC Middleware

    - by Sean
    I'm currently looking at various middleware solutions that will allow me to create applications in a variety of languages which are able to communicate amongst each other. The ZeroC product suite seems ideal as it provides a language agnostic way of defining data and the services that operate on the data (via its ICE idl) and provides support for all the mainstream languages. It also appears to offer a lot of other things we'd want, such as load balancing, grid computing and managed deployment. However, my google-fu has let me down and I'm having trouble finding information from people who have used it to implements system. I'm looking for feedback from projects that use it, and what issues/successes they had. I'm also interested in feedback from projects that evaluated it and chose not to use it (and why).

  • Best practices for managing limited client licenses/login

    - by MicSim
    I have a multi-user software solution (containing different applications, i.e. EXEs) that should allow only a limited number of concurrent users. It's designed to run in an intranet. I dont have a really good, satisfactory solution to the problem of counting the client licenses yet. The key requirements are: Multiple instances (starts) of the same application (= process) should count as only one client licence Starting different applications of the software solution should also count as only one (the same) client licence Application crash should not lead to orphaned used licences The above should work also for Terminal Server environments (all clients same IP, but different install folders) I'm looking for estabilished patterns, solutions, tips for managing used client licenses. Specific hints for the above sitaution are also welcome.

  • Does Safari have a timeout issue?

    - by woodysapsucker
    I have a website that works fine in Firefox and IE but never finishes loading in Safari 4.0.4. The live website loads a menu then loads a Google map. Using Safari, the Google map never loads. I have a test website on the same server that uses the exact same code for loading a Google map and Safari can load the map (this is the one that won't load on my live web). This test website does not have the menu - only the Google map. In both cases (live and test) the main web page calls a loadmap.js file. I've been pulling everything apart to try to identify why Safari won't finish loading. Has anyone run across any problems/solutions with Safari that may help me find a resolution to this problem?

  • DBD::Advantage and 64-bit Perl - Always 6060

    - by WarheadsSE
    I realize that I am attempting to go beyond the "supported" behavior of the manf's released drivers for perl, after all they have only released it in package with x86 .so's. However, since I cannot use their package with x64 Perl on a RHEL 5.4 x86_64 box, and maintaining a seperate install of x86 perl just for this one package, I have made an attempt to get this puppy working thanks to released 64-bit .so's that accompany other driver packages for Advantage. What I have done to this point: download beta 10 DBI drivers, in 32 download beta 10 PHP extension (it contains 32 and x86_64) copy the required DLLs into the ads-lib location (eg /usr/local/ads/lib64) compile the Perl DBI driver with the path to the lib64's .so's Good compilation, good install, good use. The problem is that I always get : failed: [iAnywhere Solutions][Advantage SQL][ASA] Error 6060: Advantage Database Server not available on specified server. axServerConnect (SQL-HY000)(DBD: db_login/SQLConnect err=-1) Does anyone have any ideas? EDIT: fixed package name in post title

  • How to document an XML Schema?

    - by lucas clemente
    I have developed a XML schema for an application I wrote. Now I want to document the valid structure for the end user, however I can't come up with any natural way to do this. I've seen things like xs3p, which essentially converts a xsd schema to a HTML representation, however that doesn't look like good documentation to me; the user shouldn't need to know anything about schemas to understand what he is allowed to do. Any ideas how to document this? Any programs / editors / graphical solutions or simply concepts I can build on?

  • Taking learning into account in a development process

    - by Thiago
    How to deal with the fact that you don't know the language/framework in a development process? For instance, suppose a group of Java developers are about to start a .NET project, they don't know the platform well and might end up finding solutions that the framework already solves or solves better. The sort of questions I have are: which are the best practices in this case? Is RTFM before going on a good pratice? When should one stop RTFM and start asking/searching/playing? Is not RTFM and just searching/asking/playing a good practice? What about estimatives? I'd like to hear from your experience :-)

  • The Project Location is Not Trusted error in Visual Studio

    - by SLC
    Quite a simple error, and the reason is obvious - I mapped a network drive, and I am opening the solution from it. Visual Studio gives me this error. I tried googling, and to my surprise, couldn't find a fix. I am running Visual Studio 2008. The solutions I found on google say I should run Mscorcfg.msc, but unfortunately, I don't seem to have that file anywhere on my computer. Nor do I seem to have anything in my control panel relating to .NET Framework. I can of course, run .NET applications fine, so the framework exists. Another solution suggested running caspol.exe, although this is .NET 2, which I also tried to no avail. Any ideas? I should add that I am trying to add the path to whatever trusted list there is.

  • Best Practices - Stored Procedure Logging

    - by hgulyan
    If you have a long running SP, do you log somehow it's actions or just wait for this message? "Command(s) completed successfully." I assume, that there can be plenty solutions on this subject, but is there any best practice - a simple solution that is frequently used? EDIT I've found an interesting link on this subject http://weblogs.sqlteam.com/brettk/archive/2006/09/21/12391.aspx Article describes using a log table, but there's an issue The logging procedure must be executed outside of any transaction I can't call that insert outside, because of cursor that I use and insert a line to that table on every row. Any ideas?

  • Multiple file types in vim

    - by Chad
    When I am working on a PHP file for example the default filetype is php. This makes sense, however when that PHP file has HTML as well the filetype is still only php. For some plugins that means that I get the PHP functionality for that plugin, but miss out on the HTML functionality. A more specific situation where this happens is with my snippet plugin. I get php snippets and not html snippets when I am editing a php file. Possible solutions to this (which I obviously don't like, hence my posting this question) are: add a map to toggle between different filetypes when I am editing different sections of the file. update my php snippets file to include the html snippets as well (while this would work for the example above, it doesn't solve the fundamental problem). So, Is there a way to edit a file using multiple filetypes at the same time in vim?

  • What some good books on software testing/quality?

    - by mjh2007
    I'm looking for a good book on software quality. It would be helpful if the book covered: The software development process (requirements, design, coding, testing, maintenance) Testing roles (who performs each step in the process) Testing methods (white box and black box) Testing levels (unit testing, integration testing, etc) Testing process (Agile, waterfall, spiral) Testing tools (simulators, fixtures, and reporting software) Testing of embedded systems The goal here is to find an easy to read book that summarizes the best practices for ensuring software quality in an embedded system. It seems most texts cover the testing of application software where it is simpler to generate automated test cases or run a debugger. A book that provided solutions for improving quality in a system where the tests must be performed manually and therefore minimized would be ideal.

  • What is the recommended toolchain for formatting XML DocBook?

    - by Jonathan Leffler
    I've seen Best tools for working with DocBook XML documents, but my question is slightly different. Which is the currently recommended formatting toolchain - as opposed to editing tool - for XML DocBook? In Eric Raymond's 'The Art of Unix Programming' from 2003 (an excellent book!), the suggestion is XML-FO (XML Formatting Objects), but I've since seen suggestions here that indicated that XML-FO is no longer under development (though I can no longer find that question on StackOverflow, so maybe it was erroneous). Assume I'm primarily interested in Unix/Linux (including MacOS X), but I wouldn't automatically ignore Windows-only solutions. Is Apache's FOP the best way to go? Are there any alternatives?

  • Avoid Internet Explorer Warning when embedding Youtube on HTTPS site?

    - by pellepim
    On a HTTPS site embedding youtube clips works great in all browser, except Internet Explorer where I get this famous little warning message: "Do you want to view only the webpage content that was delivered securely? This page contains content that will not be delivered using a secure HTTPS ... etc" I've tried to solve this in several ways. The most promising one was to use the ProxyPass functionality in Apache to map to YouTube. Like this: ProxyPass: /youtube/ http://www.youtube.com ProxyPassReverse: /youtube/ http://www.youtube.com This gets rid of the annoying warning. However, the youtube SWF fails to start streaming The SWF i manage to load into the browser simply states : "An error occurred, please try again later". Potential solutions are perhaps: Download youtube FLV:s and serve them out of own domain (gah) Use custom FLV-player and stream only FLV:s from youtube over a https proxy?

  • Incomplete results with Turkish characters in Indexing Service

    - by Ishmaeel
    Finally I get to post my i's and I's as promised... I've found that MS Indexing Service returns incomplete results when searching for documents with Turkish content. It seems to choke especially regarding the (incorrectly-named) 4I problem. Apparently, MS has fixed this problem with a Windows 2000 http://support.microsoft.com/kb/325333 service pack, but the bug seems to be resurrected with Windows XP & 2003. Anybody uses Indexing Service in their line of work? Similar problems with other non-English locales? Any solutions?

  • iframe as scriptaculous droppable

    - by Nathan
    I have a sortable list and an iframe on the same page. What I'm trying to do is define the <iframe> as a Droppable. Everything works with out errors but when I try to drag a sortable item across the Iframe it stops at the edge. ( if I move it slowly it seems works in firefox) The Iframe is set to DesignMode ="on" so covering it with a transparent element to act as the droppable does not seem applicable here. Anyone know of any other solutions or a better way to handle this?

  • Interview questions for junior C and C++ developer position

    - by Ondrej Slinták
    What interview questions should people expect as a junior C and C++ developer? Code questions or more of theory? Solutions in pseudo-code or in C code? Maybe I'm misinterpreting the word "junior", but I have no idea what would anyone ask me if I have no C work experiences. I'm bit afraid of tricky questions with pointers, so I'd like to be sure what should I look up before actually going there. I'm a junior PHP developer with 1 year of experiences, if it helps the question. Hope it isn't duplicate as I'm asking particularly about junior developer job.

  • html select option tag closes itself due to a "/" character in the dynamic value (JSP, JSTL)

    - by saky
    <select id="ordersSelect" class="drop-down" onchange="somemethod()"> <c:forEach items="${orders}" var="order" varStatus="orderStatus"> <option value="${order.id}"> ${order.publicId} </option> </c:forEach> </select> I have the above peice of code in a JSP page, that receives a list of Orders and each order has some information, the particular information that I want to display in a SELECT field is the publicId. The problem is that, on display there is only one OPTION in the SELECT and the rest of the order's publicId s are displayed as normal text below the SELECT box and not an OPTION to select. I found out that the publicId actually contains a String like A10/0001/0 and that is the character "/" is most probably causing the problem. Any solutions/suggestion/ideas?

  • .NET Framework 3.5, Assembly Binding Logging

    - by Achilles
    I am getting the following error: Could not load file or assembly 'System.Web.DynamicData, Version=3.5.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35' or one of its dependencies. The system cannot find the file specified. I've researched the problem and some of the solutions are pointing to Turning on Assembly Binding Logging. I'm confused as to what this error is. So my question: *What does this error mean and how do I resolve it? I am not hosting the site in a shared hosting scenario, it is on a single server running .NET Framework 3.5.0 using IIS 6.0 Edit .Net Framework 3.5 SP 1 isn't installed on the server. The missing assemblies are apart of that Service Pack.

  • asn.1 parser in C/Python

    - by elventear
    I am looking for a solution to parse asn.1 spec files and generate a decoder from those. Ideally I would like to work with Python modules, but if nothing is available I would use C/C++ libraries and interface them with Python with the plethora of solutions out there. In the past I have been using pyasn1 and building everything by hand but that has become too unwieldly. I have also looked superficially to libtasn1 and asn1c. The first one had problems parsing even the simplest of files. The second has a good parser but generating C code for decoding seems too complex; the solution worked well with straightforward specs but choked on complex ones. Any other good alternatives I may have overlooked?

  • Fixed footer not displaying the bottom-most list item

    - by Mohit Deshpande
    Here is my XML layout: <?xml version="1.0" encoding="utf-8"?> <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent"> <ListView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@android:id/list" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="wrap_content"> </ListView> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_alignParentBottom="true"> <EditText xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_weight="1" /> <Button xmlns:android="http://schemas.android.com/apk/res/android" android:layout_height="wrap_content" android:layout_width="fill_parent" android:layout_weight="2" /> </LinearLayout> </RelativeLayout> Which causes this problem: The listview item (outlined in red) is behind the fixed footer and cannot be used. Any solutions?

  • Correct way to get absolute url in django

    - by dreamiurg
    A problem that I stumbled upon recently, and, even though I solved it, I would like to hear your opinion of what correct/simple/adopted solution would be. I'm developing website using Django + python. When I run it on local machine with "python manage.py runserver", local address is http://127.0.0.1:8000/ by default. However, on production server my app has other url, with path - like "http://server.name/myproj/" I need to generate and use permanent urls. If I'm using {% url view params %}, I'm getting paths that are relative to / , since my urls.py contains this urlpatterns = patterns('', (r'^(\d+)?$', 'myproj.myapp.views.index'), (r'^img/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/img' }), (r'^css/(.*)$', 'django.views.static.serve', {'document_root': settings.MEDIA_ROOT + '/css' }), ) So far, I see 2 solutions: modify urls.py, include '/myproj/' in case of production run use request.build_absolute_uri() for creating link in views.py or pass some variable with 'hostname:port/path' in templates Are there prettier ways to deal with this problem? Thank you.

  • How to change the security level of a local assembly to internet or customized permission set?

    - by Jamebo
    I built a assembly which is a class library, for example lib.dll . And I also have a application to access this lib, for example test.exe. I changed the security permission for the test.exe to "intranet". At the same time, I want to change lib.dll to "Internet" like this: (Because I want to do some testing for security.) CasPol.exe -m -ag 1.2 -strong -file lib.dll lib 1.0.0.0 Internent But it seems the lib.dll can not get the security permission as I wanted. What is wrong with the command? Or maybe there are some other better solutions? Thanks -Jamebo

  • Inter Widget Communication for iGoogle like portals

    - by bakore
    I was looking for a platform where widgets developed using various technologies like Java can communicate with each other. In other words When I add widgets to an interface I need them to talk to each other. For example A Click event in one widget should trigger an event in some other widget. I have been looking into the web for solutions and ways to do it, but couldnt find anything concrete. Any pointers or information on this would be great. Something like this http://blogs.sun.com/pdblog/entry/inter_widget_communication_in_cross Google also had a gadget to gadget communication API which was deprecated last year.

  • Capturing SOAP requests to an ASP.NET ASMX web service

    - by pcampbell
    Consider the requirement to log incoming SOAP requests to an ASP.NET ASMX web service. The task is to capture the raw XML being sent to the web service. The incoming message needs to be logged for debug inspection. The application already has its own logging library in use, so the ideal usage would be something like this: //string or XML, it doesn't matter. string incomingSoapRequest = GetSoapRequest(); Logger.LogMessage(incomingSoapRequest); Are there any easy solutions to capture the raw XML of the incoming SOAP requests? Which events would you handle to get access to this object and the relevant properties?

  • Transparent Background with a Modal UIViewController

    - by Mick Walker
    I have a dilema, I want to present to the user a semi-transparent view. I found out by experimenting that if I simply pushed the transparent view to the top of my NavigationController's stack, that it would not render the transparency level I wanted. So I decided to simply add the view as a subview of the current view at the top of the stack. This solution works, the view below is still visible, and the View is 'semi-modal'. The problem is, if the parent view inherits from UITableViewController (as mine does), then the view I 'push' onto it, does not cover the navigation bar at the top. I really don't want to get into a situation where I am forced to enable / disable controls on the navigation bar every time I push this view, so I was wondering, if anyone knew of any solutions that I could use so that the view I push onto the UITableViewController will actually 'push over' the navigation bar?
